Understanding Ubuntu Versions: Naming Conventions

Ubuntu's approach to versioning and release cycles is designed to provide both stability and cutting-edge features to its users. Understanding how Ubuntu versions are named and released can help users make informed decisions about which version to install and when to upgrade. This section breaks down the naming convention and release cycle of Ubuntu, offering insights into the structure and planning behind Ubuntu releases.

Naming Convention

Ubuntu versions follow a specific naming pattern that consists of a version number and a codename. The version number is based on the year and month of the release. For example, Ubuntu 20.04 was released in April 2020. The version number is composed of the year (20) and the month (04), making it easy to identify the release date of each version.

The codename of each Ubuntu release consists of an adjective and an animal name, both starting with the same letter, in alphabetical order. For example, "Focal Fossa" for Ubuntu 20.04. This whimsical naming tradition not only adds a bit of fun to the release but also makes it easier to remember and refer to specific versions.

Upgrade Paths: Navigating Ubuntu Version Upgrades

Upgrading your Ubuntu system is a critical process that ensures access to the latest features, security updates, and software improvements. Whether you're moving from an STS to an LTS version or upgrading within the same category, understanding the upgrade path is essential for a smooth transition. This section provides an overview of how to upgrade from one Ubuntu version to another, focusing on both LTS and STS upgrades.

Preparing for Upgrade

Before initiating an upgrade, it's important to:

• Backup Your Data: Always back up important files, documents, and configurations. This ensures that you can recover your data in case of any unforeseen issues during the upgrade process.

1. Check for New Release: Use the do-release-upgrade command to check for the latest LTS release. If you're upgrading before the first point release (e.g., 20.04.1), you may need to use do-release-upgrade -d to initiate the upgrade.
2. Follow Prompts: The upgrade tool will guide you through the process, providing prompts for any required decisions.

STS to STS or LTS to STS Upgrade

Upgrading from an STS version to the next release or from an LTS to the latest STS version is a common scenario for users wanting the newest features.

1. Enable Release Upgrades: For LTS users, ensure that the Software & Updates settings are configured to notify you of any new version, not just LTS releases.
2. Upgrade Process: Use the do-release-upgrade command to start the upgrade process. The system will prompt you through steps similar to the LTS upgrade process.

General Tips

• Command Line vs. GUI: Upgrades can be performed using the terminal with the do-release-upgrade command or through the graphical update manager for a more user-friendly approach.
• Review Changes: The upgrade process will inform you of significant changes, including any packages that will be removed or installed. Review these changes carefully to avoid unexpected software loss.
